Apparatus for making no-twist yarn

摘要

An apparatus for drafting and parallelizing strands of fiber comprising three side-by-side rolls nested in three side-by-side troughs which conform to and are adjacent the bottoms of the three rolls. The rolls are rotated in the same direction at sequentially greater speeds. The first two rolls include fiber-combing teeth, and the third roll is composed of a smooth, rubber-like surface. The fibers pass sequentially around the bottoms of the three rolls through a very narrow gap between the rolls and troughs to emerge in a parallelized, drafted condition. The unit may be incorporated into a no-twist yarn system as the sole mechanism for drafting and parallelizing the fiber, to form no-twist yarn in a continuous manner; or be used in place of conventional drafting system.
